摘要： There is provided a multilayer ceramic capacitor, including: a multilayer body having a plurality of dielectric layers and a plurality of internal electrode layers alternately laminated; wherein each internal electrode layer has a width gradually decreases from a center thereof towards both ends thereof in a length direction; and when a width of each internal electrode layer at the ends thereof in the length direction is defined as a minimum width L2 and a width of a portion of a margin portion M in each dielectric layer is defined as a maximum width M2, the portion of the margin portion M having no internal electrode layer present thereon and corresponding to the ends of each internal electrode layer in the length direction, a ratio of M2 to L2 (M2/L2) ranges from 0.2 to 0.3.
